Influence of the Space Orientation of Joints in the Process of Welding on the Strength and Cyclic Crack Resistance of Welded Joints

  • Published:
Materials Science Aims and scope

We study the regularities of influence of the space orientation of a joint (at angles of 0, 30°, 45°, and 90° to the horizontal plane) for different rates of consumable-electrode pulse-arc welding (23, 40, and 57 m/h) of the sheets of AMg5M structural aluminum alloy 4 mm in thickness with the use of a ZvAMg6 filler wire on the physicomechanical properties of welded joints. It is shown that, by varying the heat input into the welded metal and the rate of crystallization of the metal in the bath, we can perform welding without using backing (forming) elements. The optimal characteristics of cyclic crack resistance of the weld metal of these welded joints are obtained in the case of orientation of joints at an angle of 30° to the horizontal plane. The preliminary monitoring of the properties of these welded joints can be performed by the nondestructive eddy-current testing method according to the specific electric conductivity of the metal.
